Us Weekly is reporting that Prince William’s stag (the Brits’ term for bachelor party) will begin this weekend.

According to the magazine’s source, there will be “plenty of booze and some legendary activities” at the bachelor bash, although exact details weren’t released because of security and privacy concerns. Younger brother Harry is expected to helm the festivities, while Kate Middleton will continue wedding plans with sister Pippa in London.

We’re not sure what these kind of celebrations are like across the pond, but between the free-flowing alcohol and Harry’s legendary party antics, we can only imagine the hangovers to come. Cheers, William! (via Us Weekly)
